PROCESS OF lvnxme METALS.

Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed April ltl 1904. Serial No. 203,423.

Be it known that we, JonN' .l). PRINCE, a resident of New York, in the, county of New York and State of New York, and IIowAIn) i S. RonGEns, a resident of Covington, in the county of Kenton and State of Kentucky, citizens of the United States, have invented a new and Improved Process of Mixing Met- Our invention relates to a process for mixing iron and zinc in any desired proportions; and its object is to mix them in such a manner that the resulting mass is homogeneous throughout, the zinc and iron being thoroughly mixed together.

In carrying out our invention we make use of the flux described and claimed by us in an application of even date filed with this application, which flux is hereby disclaimed as to this application. 'Said flux, which is particularly applicable to the process described herein, is preferably composed of sulfate of iron, sulfate of zinc, sal-ammoniac, and boric acid, all in equal parts, pulverized in form, and thoroughly mixed together.

We take any amount of zinc, depending upon the percentage of zinc that we desire in the resulting mixture of the iron and zinc, in a finely-divided state. To this we add an equal amount, by weight, of flux. The

This mixture is then covered with an amount of clear water sufficient to cover it and is left to stand for at least an hour or as much longer as may be desired, although one hour is suiticient. The liquid is then drained oil and the mass remaining thoroughly dried. After it is dried it is placed in a tube or gutter of sufficient size, so that it may be freely poured therefrom.

The iron, which has already been brought to a molten state, is then poured into a mold which is to receive the mixed metal, and as it is being run into the ate of the mold from the ladle the mixture 0 the zinc and the flux in its dry cold form is run into the mold from the tube or gutter at the same gate and at the same time with the molten iron, This causes the two metals to mix thoroughly together into a homogeneous mass.

The mixture of the flux and zinc may be poured into the molten metal as above described without being treated with water; but it is preferable to treat it as described to prevent the boiling of the boric acid in the metal.

The resulting metal comprising the mixture of iron and zinc is thoroughly homogeneous, in that the zinc and iron are in the same proportions throughout the mass, is iine-grained, and susceptible of high finish. It is adaptable for excessive high-speed journals, and its strength is increased. It is also less liable to oxidate. It is easier to machine than the other well-known hard and strong metals.

Having thus described our invention, what we desire to claim as new and to cover by Letters Patent isl. The process as herein described of pro ducing a homogeneous metal comprising a mixture of zinc and iron, which consists in melting the iron and pouring it into the mold to contain the mixed metals, while at the same time zinc in a finely-divided state, mixed with a flux, is poured into the mold, at the same gate, so that the two, the molten iron, and the dry finely-divided mixture of zinc and the flux, may unite as they flow into the mold.

2. The process as herein described of producing a homogeneousmixture of iron and zinc, bymaking a mixture of zinc in a finelydivided state and a ilux, and pouring this mixture of flux and Zinc dry into a receiver simultaneously with the pouring into it of the molten iron, the two mixing as they flow into the receptacle.

3. The process as herein described of form ing a homogeneous mixture of iron and zinc by taking zinc in a finely-divided state, of an amount to make the desired percentage with the iron, mixing it with an equal amount of the llux, also in a finely-divided state, covering the same with water and allowing it to stand, then pouring oil' the water and permitting the mixture to dry, then pouring the mixture into a receptacle at the same time. able flux at the gateway of the mold, into as molten iron is poured into said receptacle, which the metal of the higher melting-point 10 the two mixing as they are poured in. l is being poured in molten form. t
